For my graduation project (Game Design and Development) I created three characters using 3 character classes. The Tank, DPS and Support. The goal for me was to make unique characters for MOBA’s that stay recognizable even when they might be different from what we know of the current character classes.
This was the tank Chepri. You can follow the progress here: http://polycount.com/discussion/183713/wip-graduation-project-tank-dps-support#latest
